/**
* Implementation trait for class FixtureAnyFreeSpec, which is
* a sister class to org.scalatest.freespec.AnyFreeSpec that can pass a
* fixture object into its tests.
*
*
* FixtureAnyFreeSpec is a class,
* not a trait, to minimize compile time given there is a slight compiler
* overhead to mixing in traits compared to extending classes. If you need
* to mix the behavior of FixtureAnyFreeSpec into some other
* class, you can use this trait instead, because class
* FixtureAnyFreeSpec does nothing more than extend this trait and add a nice toString implementation.
*
*
*
* See the documentation of the class for a detailed
* overview of FixtureAnyFreeSpec.
